Net Entertainment has taken two classic elements of online casino games, fruit and jewels, and combined them to create King of Slots. It's a 5 reel, 25 payline title that comes with wilds, sticky wins and a bonus round that offers between 5 and 30 free spins with all things trebled. Stakes range from between 25p and £250 per spin.

King of Slots comes with 2 bonus features - first is the Sticky Win feature. Whenever you have a winning payline (or you hit 3 free spins symbols), those winning symbols will be frozen in place and the reels will spin one more time, giving you a great opportunity to add to those successful combinations and create something even bigger. The reels keep on spinning as long as there's a new winning combination on show. Get on a roll here and the results can quickly rocket.

The second major attraction in King of Slots is the Free Spins feature which is triggered when you find 5 or more scatters. Five scatters may sound a bit strong as a minimum trigger but remember the Sticky Win feature is in play which lock the free spins symbol in place and makes it much easier to hit more.

Five scatters will get you 5 free spins. Six will trigger 15 free spins with 20 on offer if you find seven. Eight scatters and it's 25 free games with 30 all yours if you hit between nine and 15 scatters. All winning spins during the free spins round are subject to a 3x multiplier and will be trebled. You can trigger more free spins here too.

Visually, NetEnt has kept things neat and simple - the reels are set against a black backdrop and include almost monochrome versions of cherries, lemons, melons and crowns as well as playing card values. There's also a standard wild which substitutes for everything apart from the scatter. Basic it may be but it's all fresh and crisp.

The gameplay gallops along at a decent rate courtesy of the sticky wins which means that the base game can deliver some impressive results. The free spins are a little harder to come by but thanks to the 3x multiplier can deliver some lucrative amounts of coins.

It may not quite live up to its lofty name but King of Slots can certainly provide some regal amounts of entertainment. It’s a medium variance game with potential wins of up to 3,000 times your stake – however, the bigger wins should almost definitely come in the free spins feature. It’s not my favourite NetEnt slot by any stretch of the imagination with Pyramid Quest for Immortality and Steam Tower highly recommended.
